Page 6: 1 General Information
1 general information the quatech, inc. Dsc-100 provides two rs-232 asynchronous serial communication interfaces for ibm-compatible personal computer systems using the pci expansion bus. The dsc-100 uses quatech's new enhanced serial adapter design. Legacy serial port data rates are limited to a max...

1.1 features the standard dsc-100 implements each of its communication channels with a 16550 uart and uses standard line driver and receiver components. For improved performance and industrial-grade reliability, quatech offers the following board upgrades: 1.1.1 "ind" option --- surge suppression up...
Page 8: 2 Hardware Configuration
2 hardware configuration the dsc-100 is automatically configured at boot time by the computer's bios or operating system. There are no required switches or jumpers to set for installation. This chapter lists a number of optional jumper settings that control various hardware features. These jumpers a...

2.3 force high-speed uart clock (x2, x4, or x8) these jumpers force an increase of the uart input clock frequency by a factor of two, four, or eight. This can allow legacy software to use baud rates above 115,200 bits per second. It is also useful if the serial port device driver does not directly s...

4 address map and special registers this chapter explains how the two uarts and special registers are addressed, as well as the layout of those registers. This material will be of interest to programmers writing driver software for the dsc-100. 4.1 base address and interrupt level (irq) the base add...
Page 12
4.2 enabling the special registers the dsc-100 contains two unique registers, an interrupt status register and an options register. These registers are enabled when the spad jumper is removed (factory default). They replace the uart scratchpad register on accesses to register address 7. The interrup...

4.4 options register the options register allows software to identify the dsc-100 as a quatech enhanced serial adapter. It also allows software to set the uart clock rate multiplier. Figure 9 shows the structure of the options register. The powerup default of the options register is all bits zero. C...

4.4.2 clock rate multiplier a standard rs-232 serial port operates at a clock speed of 1.8432 mhz. In order to achieve higher data rates, quatech enhanced serial adapters can operate at two times, four times, or even eight times this standard clock speed. This is controlled by the clock rate multipl...
